摘要：
Ruthenium-catalyzed reactions of aromatic compounds having an amino group or a heteroaromatic ring as a directing group with triethylsilane gave the corresponding ortho silylated product's in good to excellent yields. In contrast to oar previous results, in which the reactive substrates with pi-conjugation between the hetero atom in the directing group and the carbon atom possessing the C-H bond to be cleaved were used, the present reaction proceeds in cases of substrates having no such pi-conjugation.
